| 摘要: |
| 本文采用复配的石墨烯、碳纳米管和氧化铝为导热填料制备了具有导热功能的有机硅复合材料。研究了石墨烯、碳纳米管和氧化铝的复配比例对复合材料体积电阻率、导热系数、拉伸强度等性能的影响；同时,以Gr-C-4#样品为基础配方,采用硅烷偶联剂Si-G-1分别对石墨烯、碳纳米管及氧化铝进行改性,并用改性后的填料配制石墨烯硅橡胶复合材料Gr-C-Si-1#,对比样品Gr-C-4#与Gr-C-Si-1#的性能差异,分析了改性复配填料对复合材料性能的影响。采用石墨烯硅橡胶复合材料对电缆终端进行了封装,对封装好的电缆终端开展了100、150、200A电流下的温升实验,未出现局部过热,并测定水浸泡前后的电缆终端电阻,封装后的电缆终端电阻未出现明显上升,实验结果表明本材料可以在电缆终端或中间连接处进行灌封,可对封铅连接处的良好的保护作用,工程应用意义重大。 |

| Abstract: |
| Thermally conductive silicone rubber composites were prepared by using graphene, carbon nanotubes, and alumina. The effects of graphene, carbon nanotubes, and alumina on the volume resistivity, thermal conductivity, and tensile strength of composites were investigated.Meanwhile, graphene, carbon nanotubes, and alumina were modified by silane coupling agent Si-G-1. Based on Gr-C-4# sample, the modified filler was used to prepare thermal conductive silicone rubber Gr-C-Si-1#. The properties of Gr-C-4# and Gr-C-Si-1# were compared, and the effect of the modified filler on the properties of the composites was analyzed. The cable terminal was packaged with graphene silicone rubber composite material. Temperature rise experiments at currents of 100 A, 150 A and, 200 A were carried out on the packaged cable terminals.The terminal resistance of the cable before and after immersion was measured. The terminal resistance of the cable after package did not increase significantly. Experimental results show that the material could be encapsulated at the cable terminal or the middle connection, and it could protect the lead connection well, which is of great significance in engineering application. |
